You need to use the Mac OS' Disk Utility (or some third party program such as TechTool Pro or DiskWsrrior) to run a check.

What model year is the Mac? What version of the Mac OS are you running? More current versions of the Mac OS (Lion or newer) would have the recovery partition. And newer Mac will also Internet recovery. So, if it is an older Mac running a newer version of the Mac OS and the drive is corrupted, then you would need to use the recovery disc or USB drive that came with the Mac to boot from and then run Disk Utility from that.
